What Does Error FF Mean?
The LG washing machine FF error code indicates a water fill failure, commonly caused by freezing in colder environments. This error prevents the washer from operating and filling with water, often leading to ice blockages in the internal components, hoses, or pump. To resolve this issue, it's essential to thaw any frozen parts and ensure that the appliance is kept in a warmer area to prevent recurrence.

- Occurs in cold environments or after low temperature exposure
Possible Causes
- Freezing of internal water/hoses due to low temperature (high)
